To all whom, it may concern.-

Be it known that we, MILES KEHOE and ANTHONY ZILKER, both of New Albany,in the county of Floyd, and in the State of Indiana, have invented a newand Improved Furnace for Burning Bricks, of which the following is afull, clear, and exact description.

The object of our invention is to provide a new and improved furnace forburning bricks, which furnace prevents loss of heat and burns the bricksvery quickly and effectively.

The invention consists of various parts and details and combinations ofthe same, as will be fully described hereinafter,andthen pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar. letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional plan view of our in1- provement. Fig. 2 is alongitudinal vertical section of the same on the line a: at of Fig. 1.Fig. 3 is an end elevation of the same, parts being in section.

The furnace A is provided with side walls, B, and end walls, B, whichinclose the bricks C, resting on the bed or base D, provided with anumber of apertures, E, which lead into the chambers F, arranged belowthe said base D and provided with the fire-places G, carrying thegrate-bars H,upon which open the doors I.

Adamper, K, is placed over each of the apertures E in the base D, and isprovided with a guide-arm, L, passing through a keeper secured to thebase D, so as to permit of sliding the dampers K over the said aperturesE. The chambers F are preferably arranged as shown in the drawings, onebeing placed in front of the other on the sides of the fa rnaoe,andbeing .the furnace A.

divided one from the other by partitions M. The chambers F are firedfrom the ends B of Theside walls, B, of the furnace are provided witheyes or ducts N, which are in line with the apertures E.

The bricks O are set up within the walls B and B in the usual manner, soas to form the arches 0 over the apertures E. When the bricks are setup, then tires are started on the grates H and the heat passes from thereceiving-chambers F through the apertures E into the arches O andthrough the bricks O, in the usual manner. The amount of heat passinginto the arches 0 will be regulated by moving the dampers K over theapertures E by means of hooks or other tools passed into the arches 0from the outside through the ducts or eyes Nin the side walls, B.

The progress in burning the bricks can be observed at any time throughthe ducts or Preferably the kiln will be so arranged that the base I)will be level with the ground.

Having thus fully described our invention, we claim as new and desire tosecure by Let ters Patent In a briek-kiln,the combination of the walls BB, the walls B being provided with the apertures N, the base D, providedwith the apertures E, the valves K, the chambers F, and fire-places G,the said chambers and fire-places being arranged directly beneath thebase, substantially as herein shown and described.
